  1. Good evening to my fellow fossil lovers! This report has been on hold for a while, hovering near the top of my paleo-to do list. But to be honest, I haven't been on the forum as much these last few months and I've just sort of kicked the can down the road, pushing it off. Well here we are in August 2022 and I'm a whole year and some change removed from this excursion, but I say better late than never. With that out of the way lets jump into this adventure! I hope you're ready for... The Roadtrip Through Time: Colorado Part I: Pierre Shale In the winter of 2021 I ha

    Help with fossil Fish ID

    Is this a Knightia? If so, why does it look like squidward? Im only assuming it's from the Green River because I found it in a box with stuff that is definitely from the Green River.
  3. A couple of hours drive from me is an amazing spot to collect Eocene material. It's on the banks of the Brazos River (more properly, the Brazos del Dio River-The Arms of God river! My parents wrote a book on it: Exploring the Brazos: From Beginning to End). I've been to the site a few times, and always find an amazing amount of lovely little shells and such. I had the greatest luck this time though, finding a large shark tooth! I wasn't even aware that you could find shark teeth out there. I had found a cuttlefish prong there on a previous trip which is still one of my all time favorite finds
  4. In the summer of 2020 jpc and I had planned to get together in Eastern Wyoming to collect. That trip was unfortunately aborted by the coronavirus outbreak that year. This year, that conversation resumed and a new plan for a three day excursion in June emerged. I decided to make it a two week long car trip, driving all the way from New York, a longer car trip than any I've made in the past 25 years. That would afford me the opportunity to stop at some other sites on the way there and back, plus see some family. Another big reason for driving was an opportunity to visit and collect at the Big Ce
  5. I found what are claimed to be Basilosaurus jaws online, and I can't decide whether they're authentic. They definitely have real material, but I have a suspicion that they might be composites. I should also note that they are suspiciously cheap [price redacted]. First one is 15.7 inches: Second one is 24.4 inches:
  6. I’m looking for fossil collecting sites within 3 hours’ drive from Seattle to visit and do a little hobby collecting while I’m in WA for work. I’m most interested in fossil plants, mollusks, or arthropods. Can anyone give me recommendations of where to go?

    Footprint-like concretion?

    Hello, I recently visited Bawdsey, UK. I found this footprint-like object and was wondering what it could be? There is an almost scale-like pattern at the bottom of it. I found loose amongst other rocks and the Eocene London Clay is exposed at Bawdsey. The footprint-like depression is 5cm across. Thank you.

    More Lincoln Creek Bivalves

    Hi everybody! I've been in the process of trying to identify the types of mollusks I found on a recent scouting trip out to the Lincoln Creek Formation. I very much don't know what I'm doing regarding identification or preserving, so any tips will help! Regarding the bivalve, I'm wondering what I can tell with the ligaments. I feel I can safely say it's a taxodont, but I don't know where to go from there. I think that this fossil shows the imprint of the inside of the shell, and I think that the outside is well ribbed, but I think that from impressions left near this foss

    Amelia Island Bone fragments and teeth

    Found recently on Amelia island. Almost certain I have a white shark tooth as well as a dolphin vertebra? Any other specifications would be great!

    Late Eocene to middle Miocene fossils

    Some miscellaneous fossils that I found today. The top left one I think is a drumfish plate with a tooth. No idea on others…
  11. another interesting fossil. any ideas?

    Is this a fish?

    Hi everyone, my son found a very cool fossil today which I think is a fish but wondered what others think? thanks Brad

    Notogoneus osculus Cope, 1885

    Very young fish (27mm) in which the scales have not yet ossified. Juvenile specimens of Diplomystus dentatus can easily be mistaken for juvenile specimens of Notogoneus osculus. But juvenile Notagoneus can be easily recognized by the larger skull and the position of the anal fin, which is set far back. For comparison a specimen of a juvenile Diplomystus dentatus preserved on the same slab: Taxonomy from Fossilworks.org. Revised generic diagnosis from Grande and Grande 2008, p. 10. "†Notogoneus differs from all other genera in the family Gonorynchidae by the fol
  17. A few weekends ago, driving to A&M for a gymnastics meet (I'll be transferring there this fall!), I noticed a very familiar looking bridge from this forum, and the sign confirmed that barely 20 minutes away from the heart of campus is the famous Whiskey Bridge. I had no idea, so this was a very pleasant surprise. On the drive back, I decided to hit the bridge bright and early. Found a few cool inverts that are easy enough to ID with the good guides for them, but the sharks of whiskey bridge seem to be poorly written up. In fact, I couldn't find any good guides that compiled mo
  18. The assistant curator of paleontology at the Virginia Museum of Natural History is researching squamates, which includes snakes, from the Eocene Nanjemoy Formation of Virginia. A couple of friends and I have given him recently a large number of snake vertebrae, mostly from the sea snakes Palaeophis casei and Palaeophis toliapicus, from the Nanjemoy Formation of Virginia, to support his research. We will donate the specimens needed for his research. He is definitely interested in my large Palaeophis sp. vertebra in the below pictures:
  19. I just sent the below Eocene lignitized seeds/fruits from Virginia to a paleo botanist at the Smithsonian Institution, who will use a new CT scanner that makes this material vastly more interpretable than before, to study them. Since these seeds/fruits are not mineralized like petrified wood they should have been stored in Glycerin with a bit of thymol, which is an anti fungal agent, rather than in gem jar cups. You can see the discoloration of some of the foam from deterioration of the seeds/fruits over the 15 to 20 years that most of them were stored. I hope that they are still useful. I

    What is it?

    Hello! Help please to identify this fossil. Size ~4 mm. Western Ukraine. Eocene (Ypresian-Lutetian). Thanks in advance!
  21. I have several thousand well preserved shark and ray vertebrae from the Eocene of Virginia. I also have many more thousands of bony fish vertebrae from the Eocene of Virginia. See the group pictures in this post. The paper plates are 9 inches in diameter for size reference. There is very little written on fossil shark and ray vertebrae that I can find in the literature and what is written is scattered throughout a good number of different papers. I have a unique, extensive assemblage of many different vertebrae types and forms which represent the fish species from the Eocene of
  22. I was walking around an antique store here in Western NY this past weekend and found a ziplock bag of shells/coral for $7. The bag had a very nice Flame Helmet shell from the Caribbean, some pieces of recent beachworn coral, and this fossil wood section with polished end. Size 68mm x 40mm. The outer "bark" is chalcedony and the wood seems to me to be cypress or palm, possibly Eocene in age, I'm thinking US locality maybe Wyoming or ? I'm not an expert on petrified wood and will appreciate any help. Thanks
  23. A friend of mine knows some great spots for rockhounding in central Washington near the town of Cle Elum, so we took a day to go check it out. We started by driving up Old Blewett Pass where he'd previously found some stuff representing an Eocene wetland about 50 million years ago. Sure enough, the outcrops on the pass yielded some neat finds. If you zoom in, you can see that it looks like this plant had some sort of leaf spot disease in life. More leaves, excuse the shininess of the paraloid. I think this is a horsetail.

    Mystery plant structure from Eocene Washington

    Went out to central Washington with some friends yesterday to check out some fossils spots and grab some agates (trip report forthcoming). Found this on Old Blewett Pass near Cle Elum. This is either from the Chuckanut Formation or the associated Swauk Formation, both Eocene. It was found among leaf and palm frond fossils. Any ideas?
